Abstract

Fimbristylis fimbristyloides (F. Muell.) Druce (Cyperaceae) belonging to Fimbristylis sect. Fuscae Ohwi, which has been ambiguous in terms of its distribution and taxonomic substance in Korea, was found on Amtae-do Island, Sinan-gun, Jeollanam-do in Korea. F. fimbristyloides is a small species that is approximately 5-15 cm tall and differs greatly from most taxa in that the spikelets are laterally compressed. In particular, F. fimbristyloides is similar to F. ovata but is distinguished by the height of the plants, falcated leaves, the number and size of spikelets per inflorescence, glabrous styles, the size of the achenes, and the presence of achene stalks. A description, differences from related species, a key to the taxa and photographs of Korean F. fimbristyloides are provided in this paper.

그동안 한국 내 분포 및 분류학적 실체가 모호했던 식물, 납작하늘지기절(F. sect. Fuscae)의 바람개비하늘지기 [Fimbristylis fimbristyloides (F. Muell.) Druce] (사초과)를 전라남도 신안군 암태도의 바닷가 주변의 산자락 습한 곳에서 발견하였다. 바람개비하늘지기는 1년생으로 줄기는 5-15 cm 정도에 불과한 작은 식물로 소수가 옆으로 납작한 점에서 속내 대부분의 식물들과 크게 다르다. 특히, 바람개비하늘지기는 쇠하늘지기와 비슷하지만 식물체의 높이, 엽신, 화서당 소수의 수와 크기, 화주의 털 유무, 수과의 크기 및 자루의 유무 등에 의해 구별된다. 바람개비하늘지기에 대한 기재, 근연종과 차이점, 검색표 및 사진 등을 제시하였다.
